What is used for BMW G30 ECU flash

Purpose: Need to flash a BWM G series G30
Puzzle: Is the ICOM Next mandatory or is the up to date ICOM 1st generation ICOM from 2012 ok?
Can I flash NBT EVO with old ICOM?
Advice & Options:
1.
ENET cable would probably be better for you.
2.
I flashed NBT EVOs with old ICOM without problems.
3.
Flashed all Cars with ICOM Next and Online Aos with DHCP over Router. Since that i have Never any Problems with NBT or other. Flash E/F/G with this Setup.
Note that Online Aos is the online version of the BMW software for Diagnostic, Programming any many other things.

To answer your question
1st : you doesn’t need iCOM NEXT ON CnAutotool to flash the G series…but It actually Lot better & save up your times because iCOM NEXT has build in Gigabit connection.
2nd : old iCOM working find. It just take a lot longer.

Icom best any type , router I noticed w my setup I use desktop w 2 lan port and on a few f cars it actually faster then oem it programs up to 8 module same time w gigabit switch , and handle data lots faster than etnet cable and for certain modules the router is a must will crash hu high in kombi in a few others

Any icom will work , but to be safe with f,g,i series vehicles , use a dedicated router as kafas huh and a few other modules will crash if you do not use a router it handles the switches for Ethernet as those modules use more than 1 path way , in short it uses all 4 two pair wires and without router not good , this has worked for me for some time now good luck. note my router does not connect to wan
Conclusion:
ICOM Next is the best option for G series, working better and faster than old BMW ICOM cables. It handles multiprogramming and coding quite nicely. Gets the job done much faster if flashing the complete vehicle. Also, another benefit to Next will be compatibility for future cars.
